You have to keep them together for the kids to feed! If the male is to be ringed, it should be done in the first few days of life.
One thing to look out for is the kids arching their backs - if this should happen, check the yellow sticky faeces have not coagulated and blocked the anus. It does happen. Thankfully, all you need is some rubber gloves........!
It's lovely to watch little kids gambolling in the spring. Mum of course needs good food and plenty of water, warmed if you are feeling kindly.
Take lots of pictures!
